Are your air conditioner’s ducts perfectly sealed? Are you sure about that? According to the US Department of Energy, the average Maryland and Washington, DC home loses as much as 30% energy efficiency or more due to leaks, holes and gaps in their ductwork connections.

How can you tell if you have leaky ducts?

There are a number of ways to tell if you have leaky or poorly performing ducts –

  • Your summer and winter (cooling and heating season) utility bills are much higher than you expect them to be
  • You have rooms in your home that are difficult to heat and cool
  • You have rooms that are stuffy and never feel comfortable
  • Your ducts are located in an unconditioned attic, crawlspace or garage
  • You have tangled or kinked flexible ducts in your system

How can duct sealing benefit you?

If you didn’t catch it before, we’ll say it again – leaky ducts can cause your air conditioner efficiency to drop as much as 30%! Losses can be even greater if the return ducts in your HVAC ductwork have holes or gaps in them, as this will cause them to draw in air as hot as 130 F in the summer or 0 F in the winter and force them to work harder to keep the air inside your home at the correct temperature.

The benefits of duct sealing are numerous and include:

Improved comfort – sealing your air ducts can improve the overall comfort in your home by eliminating hot and cold spots and creating a more even temperature. This is especially true if you have rooms in your homes that the air conditioner or heating system just doesn’t seem to reach.

Improved indoor air quality – keeping unwanted outdoor air out of your HVAC system by sealing your air ducts has benefits that extend beyond keeping temperatures under control – it can also prevent things like chemical fumes, insulation particles and dust from getting into your ducts (and into your house). This can be especially beneficial for people in your family who suffer from asthma or bad allergies!

Improved home safety – every day, gas appliances in your home such as water heaters, clothes dryers and furnaces release combustion gases (including carbon monoxide). Leaky ductwork can cause backdrafting, where these dangerous gases are drawn back into your home instead of being moved outdoors. Sealing your ducts can help minimize the risk of backdrafting and keep your home safe from carbon monoxide and other dangerous gases.

Improved money and energy savings – leaky ducts can reduce your heating or air conditioning system’s efficiency by as much as 30%! Sealing your air ducts will increase your HVAC system’s efficiency and lower your energy bills (it even pays for itself before long!). In addition, sealing your ductwork may allow you to downsize your heating and cooling system to a smaller system that will operate more efficiently and provide better dehumidification for your home.
